Description

Physical and identifying info for Harbor Seals tagged and tracked in the San Juan Islands from 2007 to 2008, includes sex, length, weight, pelage description, and tag ID numbers.

Methods & Sampling

Dataset acquisition description

The methods below are further described in Peterson et al. (2012), Ward et al. (2012), and Thomas et al. (2011):
To estimate the movement behavior of Harbor Seals, adult seals were captured in 2007 to 2008 at several sites in the San Juan Islands: Padilla Bay, Bird Rocks, Belle Chain, and Protection Island. Several methods were used to capture seals, including boat rushes, beach sienes, and tangle-nets. Captured seals were sexed, weighed, and measured. Seals were classified as adults if they weighed more than 50 kg. All animals were flipper-tagged with unique ID numbers. Adult seals were tagged with time-depth recorders, and satellite tags were glued to the animals.
